Recent significant developments in the superstring field theory
[1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}
have ended long-term stagnation and made it possible to construct classical gauge-invariant
actions for open [12]}, [5]}, [18]},
heterotic [14]}, [16]}, [17]},
and type II [15]}, [16]}, [17]} superstring theories. It is based on
three complementary construction methods:
the formulation with the homotopy algebra structure[9]}, [10]}, [11]}, [12]}, [14]}, [15]},
the Wess-Zumino-Witten (WZW) -like formulation [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [13]}, [14]}, [15]},
and the formulation accompanied with an extra free field
[18]}, [16]}, [17]}.
The only exception is the complete WZW-like action for the type II superstring field theory,
which has not yet been constructed.
One of the purposes of this paper is to give it
and fills a gap in the WZW-like formulation.
